Mary Anderson (inventor)
Greene County, Alabama
|Died||1953 (aged 87)
Mary Anderson (1866–1953) was an American real estate developer, rancher, viticulturist and inventor of the windshield wiper blade. In November 1903 Anderson was granted her first patent for an automatic car window cleaning device controlled inside the car, called the windshield wiper.
Mary Anderson was born in Greene County, Alabama, at the start of Reconstruction in 1866. In 1889 she moved with her widowed mother and sister to the booming town of Birmingham, Alabama. She built the Fairmont Apartments on Highland Avenue soon after settling in. By 1893, Mary Anderson had moved west to Fresno, California where until 1898 she operated a cattle ranch and vineyard.
Invention of the windshield wiper
In a visit to New York City in the winter of 1903, in a trolley car on a frosty day, she observed that the motorman drove with the front window open because of difficulty keeping the windshield clear of falling sleet. When she returned to Alabama she hired a designer for a hand-operated device to keep a windshield clear and had a local company produce a working model. She applied for, and in 1903 was granted, a 17-year patent for a windshield wiper. Her device consisted of a lever inside the vehicle that controlled a rubber blade on the outside of the windshield. The lever could be operated to cause the spring-loaded arm to move back and forth across the windshield. A counterweight was used to ensure contact between the wiper and the window. Similar devices had been made earlier, but Anderson's was the first to be effective.
In 1905 she tried to sell the rights through a noted Canadian firm, but they rejected her application, saying "we do not consider it to be of such commercial value as would warrant our undertaking its sale." After the patent expired in 1920 and the automobile manufacturing business grew exponentially, windshield wipers using Anderson's basic design became standard equipment. In 1922, Cadillac became the first car manufacturer to adopt them as standard equipment.
Anderson resided in Birmingham, where she continued to manage the Fairground Apartments until her death at the age of 87. At the time of her death she was the oldest member of South Highland Presbyterian Church. She died at her summer home in Monteagle, Tennessee. Her funeral was conducted by Dr. Frank A. Mathes at South Highland and she was buried at Elmwood Cemetery.
